Why might cross-dial alignment be described as time consuming?

Cross-dial alignment can be characterized as time-consuming primarily due to the requirement for lengthy setups. This method involves the precise placement of dial indicators on machine components, which is essential for obtaining accurate measurements. The setup process often includes ensuring that the indicators are correctly calibrated and positioned, which can involve multiple adjustments and checks. Additionally, after the initial measurements are taken, there may be several iterative adjustments needed to achieve the optimal alignment, further extending the time needed for the entire process. The meticulous nature of these setups and the necessary adjustments contributes to the overall duration of the task, making it more time-consuming compared to other alignment methods that may require less detailed preparation or fewer adjustments.
